Unlike those of traditional power sources, the mechanical reliability of flexible energy storage devices, including electrical performance retention and deformation endurance, has received much attention.

What are the characteristics of flexible energy storage devices?

Flexibility is a primary characteristic of flexible energy storage devices. The mechanical deformation characterizations, analysis and structure requirements of such devices are reviewed in this work...

What are bending parameters?

Three parameters can generally describe the bending status of devices: (1) L: the end-to-end distance along the bending direction; (2) θ: the bending angle; (3) R: the bending radius of curvature. The schematics of these parameters are shown in Figure 2 b for the flexible device as a mechanical beam.
